I have learned that when you install Exchange it will ask you if Exchange will do all of the mail processing or if Exchange will connect to an ISP. &nbsp;Then you can tell it the POP server. &nbsp;Later in the installation Exchange will let you cange the email suffix if you want a different one than the Active Directory domain name. &nbsp;Thanks for your answer.

I am installing Exchange 2003 on my server. &nbsp;At the moment, all of my users have email from their ISP (@ISP.com). &nbsp;The domain name for their network (domain.com) is different than their ISP email address . &nbsp;I know how to set up Exchange to receive their ISP email (@ISP.com) and deliver it to their Exchange email account (@domain.com). &nbsp;My question is can I set up Exchange to send their email from their Exchange accoount (@domain.com) to their ISP account (@ISP.com), so that recipients outside of the network will see @ISP.com as the address rather than @domain.com? &nbsp;<br />
